I just finished reading Eden Robinson, The Sasquatch at home: traditional
protocols and modern storytelling. There is a passage that put me in mind
of the important ongoing work on food security.

Economics

[...] mentally taking notes about the irony of food fishing in the
imperial era of McDonald's. For instance, you have to [be] fairly well-off
to eat traditional Haisla cuisine. Sure, the fish and game are free, but
after factoring in fuel, time, equipment, and maintenance of various
vehicles, it's cheaper to buy frozen fish from the grocery store than it
is to physically go out and get it.

Ecology & Culture

If the oolichans don't return to our rivers, we lose more than a species.
We lose a connection with our history, a thread of tradition that ties us
to this particular piece of the Earth, that ties our ancestors to our
children.

Spent a lovely hour with the 49 pages of these lectures/stories delivered
at the University of Alberta in 2011 thanks to the non-circulating Toronto
Reference Library — nice surroundings and always stocked.
